short shaft a in bearings 'also formed as part At one end of the.

of athis bracket-support. short shaft all is'a sprocket (L12, and thereis a second sprocket als in line with the sprocket (L12, thelatter uponthe power-shaft b, said sprockets being connected by a chain, the powerand rotation being communicated by the shaft b through the sprockets aand al1-2 andthe intervening parts described to the `-sprocket or chainwheel a7 for driving the conveyer-chain ay and its pins. This powershaftl; is provided with a couplingb, receiving and secured to a smallerprolongation of said power-shaft, also carrying a referenceletter b. Thesignature-guiding trough c, Figs. 1 and 2, is at its left-hand endconnected to, and it forms a prolongation of the signature-trough a5 andextends, as shown in Fig. 2, 'to the reciprocating wire-stitchingdevices. Moving along through this trough c and in a guide c7 is aconveyer-chain c, with pins, which at one end passes around the pulleyc2, having suitable bearings, and at its other end around a sprocket c3,secured to the upper end of a vertical shaft c, aldo in suitablebearings. At the lower end of the shaft c4 there is a worm-wheel c5,occupying al horizontal position and meshing with a worm-wheel' c on anauxiliary shaft e, horizontally placed vand in suitable bearizgs in thebedfframe el of the wire-stitsbingi devices.

The power-'shaft b- 's provided with a ,sprockete (see Fig; 4) .andsaid-auxiliary shaftye with a sprocket e2, a chain ealpassing i' iaround said sprockets, so as to communicate' the power and rotation fromtheshaft b to the shaft e and fromthe shaft e, through the worm-wheels'c5 c, to the shaft c4 and and progress the superimposed pilesofsignatures or'sheets from the si nature-gathering machine to thereciprocating wire-stitching devices.

signature-trou.ghe5 at the end of the gathering-machine, and the troughccontinues this inclination; but, as illustrated in Figs. 1-2 to 1 Y 15,inclusive, this 'trough c is so bent as 1t 8o progresses in length thatthe piles of signatures or sheets are graduallyturned from an inclinedinto an almost vertical position. In factQ'they do come into a verticalposition, as

shown in Fig.- 5, at the place Where the Wire 85 stitching or staplingis performed, and in this position the stitched signatures rest upontheir folded-back edges, and I provide in connection'with thesignature-guiding trough c guide bars or racks v v" in vpairs coming at9ov opposite sides ofthe signatures and conforming to the curve of the.trough c, so that the signatures or sheets in their movementrest alikeon said bars or racksand on the trough.

The bed-frame d of the reciprocating wirei stitching devices is shownparticularly in Figs, 2', 3, and 4. a It is provided at opposite. edgeswith parallell bracket-slideways" d d2. These are in the form ofgrooves, preferably with enlarged ends, so that oil may be iilled i oointo the ends more orless to be taken up at each movement by the partssliding therein.' y f The reciprocating frame of thevwire-stitchingdevices essentially comprises the round parallel bars-ff, thecross-'barsjfQ formed to re 1o 5 ceive said parallel bars and-.onA theirunder portions to fit and. move in the slideways d d2 of the bed. At oneend f2 is a iix'ed cross-bar with apertures to receive the pms of thespools of wiresf. sent parallel fixed cross-bars at right angles to theparallel bars f f and through which said bars pass, the said cross-barsbeing pinned to the bars f f, and thus securely held, so

that the parts are obliged to move together.

h h represent movable cross -bars, and h2 a movable presser-bar, saidbars being parallel with each other and with the bars g, g', and g? andat right` angles to the barsff, through which said bars f f pass.helical spring secured at one end to the bed and at the other end to theunder side of a bar m.

Upon the left-hand end of the auxiliary shaft e thereis a bevel-gear b2,which meshes. 12 '5 with avbevel-gear b3 on a verticalshaft' b4 inbearings secured to the bed of themachine. At the upper end of thisshaft b4 thereisa crank bf", (see Figs. 2 and 3,). and a link b isat'one'end secured to the free end of/rgov' sprocket .c3 to move theconveyer-chain c Fig. lion the dotted line of 7'5 Fig. 1 showsthegeneral inclination of the4 gr gli and y? I'Gple- 1,10'

h4 represents a.r2o

This is an idle shaft, upon the respective ends of which are cranks t,and links i2 are at one end connected to the cranksv i and at theirother ends to one parallel bar f. By these devices--that is, by thebevel-gears b2 b3, shaft b, crank b5, and link b-a reciprocatingmovement is imparted to the wire stitching or stapling devices upon thebed-frame d, the series of fixed cross-bars and movable cross-bars andthe parts associated therewith upon the parallel bars f f sliding acrossthe bed in the slideways d d, these parts being compelled to move-inunison and with an even true reciprocation, because of the cranks fi andthe links i2, which with thev shaft i engage and control the respectiveends of the reciprocating frame and compel the even movement thereof,during which movement the slide-bars fj" inthe slide- Ways d d2 gatheroil from the end pockets, so

as to insure the full lubrication of the slide-l Ways during themovement.

Upon the fixed cross-bar g there are series of straightening-rollers 22, between which the wires from the spools f3f4 pass and arestraightened in their movement. One or more of these rollers isadjustable for increasing the tension or pressure'on the wire. Thisroller is illustrated in Figs. 9 and 10, in which 3 is the pin assingdown into the cross-bar g and provldedwith a hub 4 and with a contractedneck between the hub andv the pin placed eccentric to the laxis of thepin. The hub 4 is provided with a handle 5, by which the hub, neck, andpin are turned Vinthe socket in the cross-bar g so as to bring theroller 2 nearer toor take the same farther from the rollers associatedtherewith, so as to vary the applied pressure. On the fast cross-bar gthere are holdback gripping devices for the wire, each of whichvcomprises an inclined face-block 6 anda straight face-block 7, thefaces of which are separated a` distance agreeing substantially with thediameter of th roller 8. A coil-spring 9 has two free ends, one of.which is fastened to the inclined face-block 6 by a screw and the otherto the bearing-pin of the roller 9, and the wire passes between the1straight faceblock and the roller, and the function of the roller is togrip the wire against the flat face- 'block and prevent any return orback movement of t ewire which might o'ccur with the return movement ofother parts hereinafter described. y

On the movable cross-bar h there are wiregripping devices substantiallythe same as those just described upon the cross-bar gthat is, there areinclined face-blocks l0, straight face-blocks 1 1 rollers 12, andsprings,A

The shaft i is 13 with the wire passing between the straight face-blocksand the rollers, and the function of these latter devices is vto grip'the wire with a forward movement of the lmovable cross-bar h so as tocom el the wires to feed with the cross-bar an Ato pull the same throughbetween the straighteningr-ollers 2 and through between the straightfaceblocks 7 and rollers 8. Upon the movable cross-bar h there areguide-blocks 14 for the wires and through which the wires pass, and

.these guide-blocks also serve as supports and y places of attachmentfor the plunger-bars n n.'

The movable cross-bar h is madey with offset ends, in whichare securedstems 15, threaded near their ends where they pass through the ends ofthe movable cross-bar h, and nuts 16 are upon the threaded ends ofsaid'stems adapted for adjustment as hereinafter described. The fixedcross-bar g is provided with stems 17, which passthrough the movablecross-bar h/ and on which stems there are lock-nuts 18, the said stemsand lock-nuts limitin the movement-in one direction of the mova lecross-bars h h.

I em loy two bell-crank levers k 7c. (See especia ly Figs. 3 and 4.)These levers are ivoted to the under side of the fixed crossar 'g, andto the short ends of said bell-crank levers are pivotally connectedlinks Z Z, the other ends of Isaid links being pivotally connected tothe under side of the movable cross-bar h. The long ends of thebellcrank levers 7c c are pivotally connected to a bar m beneath themovable cross-bar h', the right-hand end of which bar m is of increasedwidth, (see Fig. 3,) and I provide a plate 19, secured to the bed-framed of the machine and rovided with a roller 20, against which uring themovements of the devices the broadened yend of the bar m is adapted tostrike and in its arrested position and with the reciprocatin movementof the arts hereinbefore descri ed to swing the bel -crank levers 7c 7cand impart a movement to the movable cross-bars 7L h longitudinally ofthe parallel bars ff and with said movement to draw along the wires byvirtue of the grip of the rollers 2 a distance predetermined by theposition occupied by the nuts 16 on the stems 15, the movement beingshorter or longer, according to the position of the said nuts.

The plunger-bars n n, secured upon Vthe movable cross-bar h by theguide-blocks 14, pass through between guides 21 22 on the fixedcross-bar g. This fixed cross-bar g is grooved longitudinally to receivethe cutter-bars o', upon Whichare adjustably ositioned cutters o 0,which can be set and lield in position by the clamping-screws, shownespecially in connection therewith in Figs. 6 and 7. Pivotally'mountedupon the upper surface of the fixed cross-bar g/ are rocker-bars 02, 23being the pivots ofthe lrocker-bars. These rocker-bars are of thepeculiar form shown in Fig'. 3, with jaws to receive the pins 24 in thecutter-bars o, .said rocker-bars being connected for opposite movementby a link 25, whose ends are pivotally connected to said rocker-bars.The pin 23 of thev left-hand rocker-bar, as it ap# pears in Fig. 3,passes completely dwn 1o through the fixed cross-barvg, and on the lowerend thereofthere is secured an arm 26, whose free'end bears against aportion of a bar.27, which isxed at a convenient pointv to the bed-framed of the machine. Fig.

i5 -8 shows a portion of this bar 27, whicl'i'is provided with a notchand a recessed portion, the free end of the bar 26 traveling along therecessed portion with a part of the movement v off-thereciprocatingdevices and engaging zo the notch of said bar, so as toswingth'e cutter-bars o from the position of the cutterbar in'Fig. 7 ltothe'position ofthe cutter-bar in 6,'and in so doing to cut off the wireto form the staple Vand simultaneously turn ver the cutend. of the wireYat right angles 'to the portion of the wire that isalready within theguide-blocks rrz. As the cutters o sever the wires and continue theirmovement they turn the ends cut 3o ofi" against the die-blocks r1", thesame being at right angles, as just stated, to the portions of the wiresthat are already in the .guideblocks` r r2. These die-blocks 11 r (seees- )pecially Figs. 5 and 6) ar'e 'narrow and are 3 5 ada ted forvertical movement between# the gui e-blocks r r2 i'n'waysthat are formedin the fixed cross-bar g. -Tlie lower portions of these die-blocks 1* i"are reducedand are each rovided with a helical's'pring 28v 4o betweenisks 29 andy 30v see Fig. 5,) and the lower ends of said die-blocks areprovided with an elongated 'slot receiving the' pins which connecty saiddie-blocksto the'-V cranks r3. These cranks raare on a shaft 0"4, 4S.the bearingsof which (seeFig. 5) ext d toward and are secured to thefixe-d. crossbar g. L At one end of the shaft l1A there is a crank-armT5 and link r6, (seeFigs. 3 and 4,) the free end of the link beingpivotally .connected to the movable cross-bar h', from which it will beapparent that when this crossbarhf is moved alongthe'parallel bars f f,as hereinbefore describedL that-the connection therewith of said linkr". and crank-arm rf will rock the shaft v4, `swinging the crank 13' anddrawing down'the die-blocks#| r. lThis movement is to be timed with themovement ofthe plunger-bars fri/ n', so that. after'tli'e wires are cutand the staplesV formed bybending the ends against said dieeblocks Vandthe presser-bars bear 'against the ends of the v` staples to force thesame intol the superintposed signaturesor sheets Vthat the diefblocksdraw down as the presser-bars move forward,

the staples sliding up overtheinclined upper vable along the cross-bart3 with' th with a roller 38, running on thev peribearing-'surface ofacam 39, secure .onthe forming the essential functionof assisting in thestaple is pushed for-ward.

Within or just beneath the movable crossbar h2 is placed abar s,provided'with notches ends? ofv the `dieblocks, said die-blocks per .j

to receive the rollers s, which rollers arepivoted to the said cross-barh2, and I providev .dogs s2, also pivoted to the under side of themovable cross-bar h2' and coming between the facexof the bar s' oppositethe notched face and the surface of the superimposed signatures orsheets as they rest in the guideway against a fence I providea post s-clon the frame of the machine, against which with the reoiprocation of theparts the righthand'end of thebars strikes and which-when arrested,is-moved `longitudinally `to a suffinotches receiving the rollers andbring the doing toswing the dogs s2. As' these dogs are'. swung withthetimed movement of the parts they come against the ends of the wirestaples protrudingfrom the signatures of the 852.; cient extent to throwthevbar out of the.

t t. are toggle-bars pivotally vconnected to the shaft t?, the ends' ofwhich are in bearings on the cross slide-bar f. toggle-bars is .made toa toggleshaft 32 and shaft`f33 is in bearings in the movable-crossvbarh2, and to said shaft is connected a link 34, extending downward in themachine.

Thelend of` the link.34 connected "to "the in lthe frame of the machine.The upper ends of the cranks 35 are connected by a crossnotched toreceive said cross-bar and is movcatory movement'of the parts.` n

The joint of the -the'freev ends of the toggle-bars are connected ato ashaft 33, to which they are keyed. This cranks 35,secui'ed-to ashaft 3 6in bearings 'n e recipro Acrank 37, fast on the haft 36, (see 4,).l

hery or auxiliary shaft 'e ,and withfthe rotation of this` auxiliaryshaft e and thecamf39 the..`

roller 38and crank 37 swing the-'shaft 36'and i2 bars h2. This movementfromfthe position of the partsshown in Figi 4 straightens-the rtoggle-bars, and as one endof the toggle-bars is fastened to thecross-bars f it follows that the straightening of the toggles must movethe cross-bar h2, and this movement is t0- ward the receptacle for thesuperimposed signatures or sheets to be bound, and the action of saidparts is to come in contact with the back surface of the signatures orsheets and press the same tightly against the fence w, and this pressureis exerted coincident with the movement of forcing the wire staples Ithrough the superimposed signatures or sheets, and the pressure ismaintained in the timed movement of the parts until the righthand end ofthe bar s strikes the post s3 and swings the dogs s2 to overturn andclench the staples in position.'l The spring 31, at one end secured tothe cross-bar h2 and at the other end to the bar s, serves to return thebar s to the initial position shown in Fig. 3 when this pressure isreleased and the dogs s2 are free therefrom.

I provide a threaded bar 40, at one end secured in a boss on the uppersurface of one slide-bar f', and this threaded bar passes through thefixed cross-bar g2 and is provided with nuts 41 thereon at oppositesides of the cross-bar g2 in order that the adjustment of thewire-stitching devices may be provided to accommodate pamphlets ormagazines of different thicknesses-that is, of different numbers ofsignatures and sheets-this adjustment being mainly apparent at the artshown particularly in Fig. 5, because W Aere the pamphlet or magazine isof a less number of sheets and the parts are adjusted the loosecross-bar h2 would then be brought nearer to the cross-bar g, thusreducing the space between the fence 'w and the adjacent and opposite'face of the cross-bar h2, and where a larger pamphlet is to be providedfor the adjustment in the other direction will take the fence w awayfrom the face of the cross-bar h2.

I provide and have shown in Figs. 2 and 4 a trough u, supported at oneend by a bracket 42 on the side ofthe machine and at the other end by apost 43, secured to the Hoor. This trough in cross-sectin is ofbroadened -V form and is so laced that the superimposed signatures orsfieets as stitched by the reciprocating stitching mechanism aredelivered directly from the machine into the trough. I have shown andprefer to employ a reciprocating finger-bar u and packer-plate fw*secured thereto, moving through. the trough and actuated by a link ua,at one end pivoted to the finger-bar andv at the other end to vaflywheel u2 on the end of the axle-shaft e. This device with themovement of this auxiliary shaft feeds the pamphlets or magazines alongthrough the trough tomake way for others that are coming from thestitching mechanism. A

I have shown in Figs. 3 and 17 studs 45 on the fixed cross-bar g inproximity to the series gaged by the conveyer-chain c with pins andmoved along the signature -guiding trough c, their inclination being pro4ressively increased toward the vertical, as s own in Figs.v l 1 to 1 5.As they reach the reciprocating Wire stitching .or stapling -devicesthey come into vertical position, as shown in Fig. 5, between vthe fencew and the movable cross-bar h2.V

Pressure is applied not only to hold but to consolidate t e signaturesand sheets by the toggle-bars t t', which are in pairs and which areactuated, as hereinbefore described, by l the link 34 traveling alongthe cross-bar t3 at the upper ends of the cranks 35, the cranks beingfast upon a shaft 36 and actuated by lthe crank 37, roller 38, and cam39 upon the Z auxiliary shaft e.

This movement of the link 34 on the bar t3 permits of the reciprocationof the wire-stitching devices and at the same time makes possible theaction of the mechanism-that is, the toggle bars-for gripping and at thesame time holdingl the superimposed signatures and sheets. hereinbeforedescribed, the wire-stitching devices are reciprocated by the auxiliaryshaft e, by bevel-wheels revolving the shaft b4, and by the crank b5 andlink bs, the movement being insured and steadied by the shaft t', cranksft, and links i2, the feeding movement bein effected vby the bell-cranklevers k k', whic are pivoted to the fixed cross-bar g, the links Z,connected to their short ends and pivoted to the movable cross-bar h',and the bar m, pivoted to the long ends of the bellcrank levers comingagainst the fixed stop or roller K20. y

for preventing back movement have also die-blocks r 1", the staplesthereafter being4 forced by. said plunger-bars through the guide-blocksr r2 and through the superimposed signatures or sheets and clenched onthe opposite side by the dogs s2 being actuated by the bar s when thesame strikes the post sa. As the reciprocating wire-stitching devicescome to the right hand of Fig. 3 and at each movement thereof in saiddirection a book is delivered into the trough u. These reciprocatingdevices are returned to an initial 'osition likewise by the shaft b4,crank b5, and ink b, and in said return movement the spring h4, actingupon the bar m, returns the bell-cranlr'llever devices (shown in Fig.16) to i an initial position in which the wires while held by thegripping devices 6, 7, 8, and 9 are rengaged by the gripping devices1011, 12, and 13 for a new hold on the wire, and the bar 27, acting uponthe arm 26 and the parts hereinbefore described and connected there`-with, serves to return to an initial position the cutters ready torepeat the operations hereinbefore described. f

While I have shown in the drawing two lwires and devices acting thereonto form them into staples, it may be remarked that the devices of'myimprovement are equallyv applicable for any number of associateddevices, so that the signatures and sheets forming a book may heconnected by two or more staples, as desired.

The fixed cross-bar g is recessed at us in its upper face (see Figs. 3,4, and 17) to receive cotton waste and oil. The wires. as they -passfrom the reelsf 3 f1 take u p su'licient oil A as they pass through orcomein contact with the cotton-waste Vto lubricate the same and theparts through and between which the wires pass.
